Google Chrome

I'm having issues when I attempt to create chess diagrams in forum posts. I can create and post the game just fine, but I cannot add "!!", "!?", etc. onto moves that I'd like to highlight. To be a bit more specific, the drop-down menu is available, but the indicators are not saved or posted with the game.

I'm using Chrome 12 on a Windows 7 32-bit system. I'm relatively sure that the browser is the issue, since I can add the markers when I use Firefox.

Are there any other Chrome (or other browser) users out there who are having this issue?
